REINFORCED-CONCRETE WALL STRUCTURE.

Specification of Letters Patent.

Patented J une 22, 1920.

Application filed September 22, 1919. Serial No. 325,292.

To all whom it may concern:

Be it known that I, Vlooo J. MADSEN, a citizen of the United States,residing at Fargo, in the county of Cass and State of North Dakota, haveinvented certain new and useful Improvements in .Reinforced- ConcreteWall Structures; and I do hereby declare the followin to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it itppertains to make and use thesame.

y invention relates to improvements in reinforced concrete wallstructures, and is in the nature 'of an improvement on my copendinapplication filed February 16, 1918, under erial Number 217,687,entitled concrete block; and has for its primary object to continue theair spaces between the laterally spaced slabs through the intermediatepiers so as to form a single continuous air space in each wall whichextends the full distance between the corner piers.

.of the novel devices and combinations of devices hereinafter describedand defined in the drawings.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings Figure 1 is a fragmentary perspective view ofa wall constructed in accordance with my present invention; and 1 Fig. 2is a plan view of the same.

The numeral 3 indicates a foundation, which may be composed of anysuitable material, upon which is supported and secured by means ofanchor rods 4: a wall constructed in accordance with my presentinvention.

The improved wall structure includes corner piers 5, only one of whichis shown, pairs of intermediate piers 6 laterally spaced to afford airspaces 7 therebetween, and concrete slabs 8 also laterally spaced toform air spaces 9 which continue into the air flf'aces 7 to form asingle air space which covrs the entire area of the wall and extendsfrom one corner post to the other.

Each corner pier 5 comprises pre-formed superimposed concrete blocks 10having in each of their wall faces laterally spaced vertically alinedgrooves 11 and also having vertically alined openings 12 into which thecorner anchor rods 4 extend. Each intermediate pier 6, of each pair,also comprises pro-formed superimposed concrete blocks 13 having in eachof their wall faces vertically alined grooves 1 1 and also having alinedopenlngs 15 into which the intermediate anchor rods 4 extend. Thesuperimposed concrete slabs 8 are interlocked with the piers 5 and 6 byvertically sliding the same into the grooves 11 and 14, as best shown inFig. 2. he joints in the structure, wherever reiuired, are luted withmortar or cement.

xtending through the alined openings 12 in each corner pier 5 is avertical tie-rod 16 preferably located, as shown, at the intersection ofthe longitudinal centers of the outer slabs 8, and a vertical tie-rod 17is extended through the alined openings 15 in each intermediate pier 6.The lower end portions of the rods 16 and 17 overlap the upper endportionsof the anchor rods 4, as best shown in Fig. 1. i

The intermediate piers 6 of each pair are connected between the blocks13 at various different elevations by transverse tie-rods 18 havinghook-like ends which are interlocked either with the respective anchorrods 4 or the rods 17, depending on the elevation at which said tie-rodsare located. The two outer. intermediate piers 6, adjacent to the cornerpost 5, and on opposite sides thereof, are connected to said cornerpier, to afford a reinforced corner structure, by horizontal angletie-rods 19 having hook-like ends which are interlocked with therespective anchor rodsxl or tie-rods 17, depending on the elevation atwhich they are located. The angle portions of the rods 19 extend aroundand outward of the tie-rods 16 and thereby anchor the respective piers 6to the corner pier 5'. These tie-rods 19 are laid, at various differentelevations, between the upper and lower faces of certain of the outerslabs 8, blocks 10 and blocks 13, as best shown in Fig. 2.

he alined openings 12, in the corner pier 5, are filled with a body ofconcrete 20 and, likewise, the alined openings 15, in each intermediatepier 6, are filled with a body of concrete 21. These bodies of concrete20 and 21 extend from the foundation 3 to the tops of the piers 5 and 6,and have embedded therein the anchor rods l and vertical tie-rods 16 and17.

The ends of the transverse tie-rods 18 are embedded in the concretebodies 21 of each laterally spaced pair of intermediate piers 6, andrigidly connect said bodies to hold the said pair of piers. properlyspaced. The

angle portions of the horizontal tie-rods 19 are embedded in theconcrete body 20 and the ends thereof are embedded in the concretebodies 21 of the respective outer intermediate piers 6 andthereby'rigidly anchor the said concrete bodies 21 to the concrete bod20.

V hat I claim is 1. A wall structure including corner and laterallyspaced pairs of intermediate piers, each of said piers comprisingsuperimposed concrete blocks, said intermediate piers being laterallyspaced to afford horizontal ventilating passageways therebetween, saidcorner pier having in each of its wall faces two laterally spacedgrooves, each intermediate pier having in each of its wall faces asingle groove, and pre-formed concrete slabs positioned in said groovesbetween the piers.

2. A wall structure including corner and laterally spaced pairs ofintermediate piers, each of said piers comprising superimposed concreteblocks, said intermediate piers being laterally spaced to affordhorizontal 25 ventilating passageways therebetween, said corner pierhaving in each of its wall faces two laterally spaced grooves, eachintermediate pier having in each of its wall faces a single groove,pre-formed concrete slabs positioned in said grooves between the piers,said superimposed concrete blocks having alined openings filled withbodies of concrete, vertical tie-rods embedded in, said bodies ofconcrete, transverse tie-rods connecting the vertical tie-rods of eachpair of intermediate piers, and horizontal tie-rods connecting thevertical tie-rods -in one of the intermediate piers on each side of thecorner pier with the vertical tie-rod in said corner pier.

In testimony whereof I affix my signature in presence of two witnesses.
